Once upon a time, Google dared to experiment with HTTPS encryption for their search instead of allowing all search data to go unencrypted through the wire. For this experiment, they created a new subdomain: encrypted.google.com was the address where your could get some extra privacy. What some people apparently didn’t notice: the experiment was successful, and Google rolled out HTTPS encryption to all of their domains. I don’t know why encrypted.google.com is still around, but there doesn’t seem to be anything special about it any more. Which doesn’t stop some people from imagining that there is.
